Cannot turn on the heater, most importantly, also some of the other features

Hello, thank you for using Howly. I’ll be happy to help you out! May I ask your name?

Nice to meet you, *****!
Were those features working before?

I see. Was it bought brand new?

Got you!
Did you connect all the wiring?

Oh, I see, thank you!
Do you have a remote control for this fireplace?

Noted.
Does it respond, when you press the fire button?
And could you please follow these steps:
1. Turn the unit off and unplug the unit for 5 minutes.
2. Plug back in and turn on the unit.
3. Turn off a circuit breaker that supplies electricity to the unit and wait 5 minutes.
4. Flip the circuit breaker back on.

Noted.

Also, try this:
1. Change the battery for the remote control.
2. Check to make sure the master switch is turned on.
Thank you, please, keep me tuned if there will appear any issues or additional questions!

Did it work, *****?

Touch the Fire icon button once to activate the heater at its low level (the icon will light up) to activate the heater at its low level (700W). Touch the button once more to active the heater at its high level (1350W). When set in high level, touch the button once again to deactivate the heater.

Are you sure it's working properly, *****?
